Margot Robbie not only pulled off the stealthiest wedding Hollywood has (or rather, hasn鈥檛) seen in ages, but confirmed the big news by showing off her wedding ring in her very own quirky (and bada$$) way. And now it turns out there was something else totally unique about Margot鈥檚 nuptials to new hubby, Tom Ackerley. Instead of opting for a custom piece or off-the-rack stunner, the Suicide Squad actress chose to wear her mother鈥檚 wedding dress.

30 years ago, Margot鈥檚 mom, Sarie Kessler, wore the white-cream off-the-shoulder lace dress to her own wedding. With Margot having a famously close relationship with her mom (even paying off the mortgage on Sarie鈥檚 home back in 2014), it totally makes sense that this particular daughter would make such a sentimental choice.

Australia鈥檚 Courier-Mail confirmed that 26-year-old Margot had the 鈥渧intage鈥 dress altered by high-profile Gold Coast designer Casey Tanswell just a week before the big day, then added a little of her own style by opting for a gold pendant necklace and wearing her hair down in loose curls pinned back with no veil.

Though there are no clear pics of Margot鈥檚 wedding day look (seriously, they did such an impressive job of keeping their special day private), it sounds simply lovely and sentimental AF.
